FIELDThe present invention is related to a battery carrier apparatus, and more particularly related to a battery carrier apparatus that has flexible structure.
BACKGROUNDIn recent years, the use of batteries has become increasingly prevalent in a variety of environments, including home backyards, parks, farms, and other outdoor settings. Batteries are now commonly used to power a wide range of equipment and tools, providing a convenient and portable source of energy for numerous applications. This shift towards battery-operated devices has revolutionized the way many tasks are performed, particularly in gardening and landscaping.
Gardening tools such as lawn mowers, hedge trimmers, and leaf blowers often rely on battery power to deliver the necessary energy for efficient operation. These tools benefit from the portability and ease of use that batteries provide, allowing users to work without the constraints of power cords or the need for nearby electrical outlets. Additionally, battery-operated tools are generally quieter and produce fewer emissions compared to their gasoline-powered counterparts, making them more environmentally friendly and suitable for use in residential areas.
In home settings, batteries are extensively used to power a variety of devices and equipment. From cordless drills and saws to lighting fixtures and outdoor entertainment systems, batteries offer a versatile and reliable energy source. This widespread adoption of battery technology in household applications enhances convenience and flexibility for homeowners, enabling them to carry out tasks and enjoy their outdoor spaces with minimal hassle.
Public parks and recreational areas also benefit from the use of battery-powered equipment. Maintenance crews often use battery-operated tools to perform tasks such as trimming, edging, and clearing debris. These tools not only contribute to a quieter and cleaner environment but also improve the efficiency and effectiveness of park maintenance operations. The use of batteries in public spaces helps to maintain a pleasant atmosphere for visitors while reducing the environmental impact of maintenance activities.
Farms and agricultural settings are increasingly incorporating battery technology into their operations as well. Battery-powered tools and equipment, such as electric chainsaws and pruners, are commonly used for tasks like tree trimming, crop maintenance, and general farm upkeep. The portability of these tools allows farmers to work in remote areas without access to traditional power sources, thereby improving productivity and reducing reliance on fossil fuels.
Despite the many advantages of battery-powered tools and equipment, there are also some notable drawbacks. One significant issue is the weight of the batteries themselves, which can make them cumbersome to handle and transport. This is particularly problematic when multiple batteries need to be moved simultaneously, either for recharging or to different work areas. The challenge of transporting heavy batteries can hinder efficiency and increase the physical strain on users, especially in larger outdoor environments where distances between work areas and charging stations can be substantial.
In addition to being cumbersome, batteries also require regular recharging, which presents another layer of complexity. When multiple devices are in use, each requiring its own battery, managing and recharging these batteries can become a significant logistical challenge. This is especially true in environments where numerous battery-operated tools are in operation simultaneously, such as large gardens, parks, and farms.
The need to frequently recharge batteries means that users must often interrupt their work to replace depleted batteries with fully charged ones. This can lead to downtime and inefficiencies, particularly if there is a limited number of spare batteries available. Users must also remember to recharge batteries after each use, a task that can easily be overlooked in the midst of busy work schedules, leading to situations where tools are not ready for use when needed.
Managing multiple batteries also involves keeping track of their charge levels and ensuring that each battery is properly maintained. Over time, batteries can degrade if not cared for correctly, losing their ability to hold a charge and thus reducing the overall productivity of the tools they power. Effective battery management requires a system for monitoring battery health and usage, which can be time-consuming and difficult to implement without the right tools and knowledge.
Recharging batteries also requires access to suitable charging facilities. In many outdoor environments, especially remote areas of farms or large parks, access to electrical outlets may be limited. This necessitates the transportation of batteries to central charging locations, further complicating the process. The physical effort required to move multiple heavy batteries to and from charging stations can be considerable, adding to the overall burden on users.
Moreover, coordinating the charging of multiple batteries to ensure that they are all ready for use when needed can be a daunting task. Different batteries may have varying charge times and capacities, and without a systematic approach to charging, some batteries may be overcharged while others remain undercharged. This can lead to inconsistent performance and shorten the lifespan of the batteries, increasing costs and reducing the efficiency of battery-operated tools.
The complexity of managing and recharging multiple batteries highlights the need for effective solutions that can streamline these processes. Such solutions should address the physical challenges of transporting heavy batteries, provide reliable methods for monitoring and maintaining battery health, and offer convenient and accessible charging options. By improving the efficiency of battery management and recharging, users can maximize the benefits of battery-powered tools while minimizing the associated difficulties and inconveniences.
Given the increasing reliance on battery-powered tools and equipment in various environments, it is clear that addressing the challenges associated with battery management and transportation is essential. The cumbersome nature of batteries, coupled with the need for regular recharging, underscores the importance of finding efficient solutions. These solutions must streamline the movement and maintenance of batteries, ensuring that they are always ready for use and that their longevity is maximized.
It is beneficial, therefore, to design a device specifically aimed at making the movement of batteries easier while also providing convenient management and charging capabilities. Such a device would alleviate the physical strain involved in transporting multiple heavy batteries and reduce the logistical complexities of keeping them charged and operational. By integrating features that facilitate easy movement and systematic charging, users can enjoy uninterrupted productivity and more efficient use of their battery-operated tools.
In conclusion, a thoughtfully designed battery carrier apparatus would significantly enhance the usability and effectiveness of battery-powered equipment in various settings. By addressing the key challenges of weight, transportation, and recharging, such a device would offer a practical and reliable solution to the growing demand for efficient battery management. This would not only improve the overall user experience but also extend the operational life of batteries, providing a sustainable and cost-effective approach to powering a wide range of tools and devices.

The present application particularly relates to a trailer energy station. Considering the compatibility of the trailer energy station with the towing vehicle and the flexibility of transportation, the trailer energy station should not be too large in volume. Therefore, how to arrange more storage and charging equipment and garden tool storage space within a limited space is a key design focus of the trailer energy station.
The structure of existing energy stations is generally square, which does not fully utilize some auxiliary spaces around the compartment, especially the arm area at the front of the compartment. It should be understood that, to avoid collision between the trailer vehicle 1-10 and the front towing vehicle during turns, the arm 1-13 of the trailer vehicle 1-10 is generally set to extend forward with sufficient length in a triangular structure. This structure occupies part of the length of the vehicle, and regardless of the compartment length, the length of this part of the arm 1-13 must be reserved. However, existing energy stations do not fully utilize the longitudinal space above the arm 1-13. The present application addresses this issue by setting an additional storage space at the front of the traditional compartment. The front end of this storage space is designed to be retracted, fully utilizing the area above the arm 1-13 without interfering with the vehicle's steering. The following will provide a detailed description of the technical solutions of the present application in conjunction with specific embodiments.

In one embodiment, the security detection function can be networked with the alarm system of relevant law enforcement departments, and a positioning module can be installed in the energy station to enable law enforcement personnel to quickly reach the scene for disposal in the event of theft or robbery.
Please refer to
In one embodiment, the configuration of the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 in the safety detection module is unified, meaning that the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 can be uniformly configured to be normally open or, in the system initialization phase, the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 can be in a closed state. Users can start the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 uniformly through the operation button, and likewise, users can also uniformly close the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 during subsequent operations. Of course, the security detection submodule 2-1002 and the disaster detection submodule 2-1003 can also be indistinguishable, and users cannot configure them separately, but can only uniformly turn on or off all submodules through the operation button.
In one embodiment, users can also customize the selection of the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 in the safety detection module, meaning that users can choose the detection modules to be activated in the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 according to their needs. Of course, the security detection submodule 2-1002 and the disaster detection submodule 2-1003 can also be indistinguishable, and each module can be individually selected to be activated or deactivated by users.
In other embodiments, the definition can also be made according to the attributes of the disaster, for example, the detection modules belonging to the category of natural disasters can be directly defined as normally open and cannot be turned off.
In one embodiment, the safety monitoring system can have the following multiple response modes for the abnormal information detected by the safety detection module:
Alarm only, no action: when one or more submodules in the safety detection module detect an abnormality, the safety monitoring system only alerts the user to the abnormality without any action, leaving it to the user to decide whether to handle it. For example, when the flame detection unit detects a flame point, the safety monitoring system only pushes alarm information, which can be displayed on the display screen inside the energy station or on a mobile terminal.
Alarm, delayed action: when one or more submodules in the safety detection module detect an abnormality, the safety monitoring system alerts the user to the abnormality and will take action after the abnormality persists for a preset time. For example, when the flame detection unit detects a flame point, the safety monitoring system pushes alarm information to alert the user to the abnormality and, after the abnormality persists for a preset time, the safety monitoring system triggers the alarm through sound and/or light alarms. In other embodiments, the action can also be understood as a direct solution to the problem, such as the safety monitoring system can be equipped with a fire extinguishing device. When the flame detection unit detects a flame point, the safety monitoring system pushes alarm information to alert the user to the abnormality and, after the abnormality persists for a preset time, automatically activates the fire extinguishing device to extinguish the fire.
Alarm and immediate action: when one or more submodules in the safety detection module detect an abnormality, the safety monitoring system alerts the user to the abnormality and immediately takes action. For example, when the flame detection unit detects a flame point, the safety monitoring system pushes alarm information to alert the user to the abnormality and triggers the alarm through sound and/or light alarms. In other embodiments, the safety monitoring system can be equipped with a fire extinguishing device. When the flame detection unit detects a flame point, the safety monitoring system pushes alarm information to alert the user to the abnormality and immediately activates the fire extinguishing device to extinguish the fire.
Of course, besides the flame detection unit case, the smoke detection unit can also be linked with the air conditioning system in the energy station to activate the ventilation mode of the air conditioning system when the smoke detection unit detects smoke in the compartment. Additionally, the water immersion detection unit can be linked with the drainage device in the energy station to activate the active drainage function when the water immersion detection unit detects water entering the energy station. Regarding the above multiple response modes, users can select different operation modes according to the actual application scenario or work needs.
Of course, in other embodiments, the safety monitoring system is only configured with one of the following multiple response modes: alarm only, no action; alarm, delayed action; alarm and immediate action.
In other embodiments, the safety monitoring system can also automatically match the response mode of abnormal alarms according to the severity of the abnormal alarm information detected by a single submodule or multiple submodules. In specific application scenarios, the detection results of the security detection submodule 2-1002 and/or the disaster detection submodule 2-1003 can be divided into multiple levels based on severity. Different levels correspond to different response modes, such as the mild abnormal level matching the alarm only, no action response mode; the moderate abnormal level matching the alarm and delayed action response mode; and the severe abnormal level matching the alarm and immediate action response mode. In more severe cases, the system can also directly control the entire vehicle to power off to reduce losses.
In one embodiment, the alarm actions mentioned above can be completed by submodules in the safety detection module, meaning that the submodules perform data collection and independently judge abnormalities and alarm actions, and then upload the corresponding data to the central control gateway 2-1001 or the cloud server. For example, when the smoke detection unit detects smoke inside the energy station, it directly alarms through the sound and/or light alarms on the smoke detection unit and outputs a high-level signal to the central control gateway 2-1001 or the cloud server to inform the central control gateway 2-1001 or the cloud server that the smoke detection unit has detected an abnormality in the environment. The high-level signal indicates an abnormality, while the low-level signal indicates normality. Of course, in more intelligent smoke detection units, other related information can also be uploaded, such as smoke concentration and the main components of the smoke.
Of course, in other embodiments, the submodules in the safety detection module can also perform data collection and upload the collected data to the central control gateway 2-1001 or the cloud server, where the central control gateway 2-1001 or the cloud server analyzes the data collected by the submodules to determine whether there is an abnormality and perform alarm actions.
The disaster detection submodule 2-1003 of the present invention includes detection units not limited to the types mentioned above. In practical applications, corresponding detection units can be set according to the actual working environment of the energy station. For example, when the energy station works in a high-temperature environment, a temperature detection unit can be set to monitor the temperature. When the temperature exceeds the preset safe temperature, the central control gateway 2-1001 can issue a high-temperature warning to the user through the cloud server 2-2000, or the central control gateway 2-1001 or the cloud server 2-2000 can automatically activate the air conditioning system to cool the energy station. Additionally, when driving on rough terrain, a tire pressure detection unit 2-1007 can be set to obtain tire pressure data in real-time, allowing timely maintenance measures when a tire blowout occurs.

Based on the above safety monitoring system, a safety monitoring method provided by one embodiment of the present invention is as follows:
The central control gateway 2-1001 receives the detection data sent by the safety detection module;
The central control gateway 2-1001 determines whether there is abnormal information in the energy station based on the preset state and the detection data;
When there is abnormal information, the central control gateway 2-1001 extracts the target video data collected by the image acquisition unit 2-1004 within a preset time period and sends the target video data and the abnormal information to the cloud server 2-2000. The cloud server 2-2000 receives the abnormal information and pushes alarm information to the mobile terminal 2-3000 based on the abnormal information. Specifically, the abnormal features in the target video data are identified, and the abnormal features are compared with the abnormal information. When the abnormal features match the event represented by the abnormal information, the alarm information is pushed to the mobile terminal 2-3000.
In specific embodiments, the mobile terminal can provide a visual interactive interface, as shown in

The power-receiving device 4-40 communicates and connects with the transmission control module 4-30 for charging through the battery management unit 4-42 and charges the internal battery packs.
It should be noted that, in some embodiments, the power-receiving device 4-40 can also be an electric vehicle or other equipment that requires charging. In this case, it is only necessary to change the structure of the charging interface 4-34 of the transmission control module 4-30 to match the charging interface 4-34 of the electric vehicle, using a charging pile for electric vehicles as the charger 4-10, connected to the communication control module 4-20.

It should be noted that, during the startup state of the charging system, an AD detection signal can be continuously maintained in the AD communication loop. Since adding a new transmission control module 4-30 will interrupt the AD communication, making it impossible to receive the AD detection signal returned through the AD communication loop, it is possible to use whether the returned AD detection signal is received to determine whether a new transmission control module 4-30 has been added. The newly added transmission control module 4-30 will remain silent until it is allocated a communication address.
It should be noted that, during the charging process, when a new transmission control module 4-30 is added to the directional power delivery system, the following two methods can be used to allocate addresses to the newly added transmission control module 4-30:
First: When the communication control module 4-20 detects that a new transmission control module 4-30 has been added to the directional power delivery system, it immediately stops charging, and the communication control module 4-20 reallocates addresses to all transmission control modules 4-30 in the directional power delivery system via the AD communication loop.
Second: Wait until the currently charging power-receiving device 4-40 finishes charging. The transmission control module 4-30 corresponding to the completed charging power-receiving device 4-40 will send a charging completion command to the communication control module 4-20. Upon receiving the charging completion command, the communication control module 4-20 reallocates addresses to all transmission control modules 4-30 in the directional power delivery system via the AD communication loop.
In one embodiment, when multiple power-receiving devices 4-40 are connected through transmission control modules 4-30 in the charging system, the communication control module 4-20 can charge each power-receiving device 4-40 connected to the transmission control modules 4-30 one by one according to the series order of the transmission control modules 4-30 in the directional power delivery system. It should be understood that, in other embodiments, other preset rules can be used to charge each power-receiving device 4-40 connected to the transmission control modules 4-30.
In one embodiment, when charging a power-receiving device 4-40 of a particular transmission control module 4-30, the communication control module 4-20 can send a silence command to all transmission control modules 4-30 via the CAN bus or AD communication loop. The transmission control modules 4-30 will adjust their communication status based on their charging status upon receiving the silence command. If they are in a charging state, they maintain normal communication status. If they are in a non-charging state, they maintain a restricted communication status. Transmission control modules 4-30 in a restricted communication status do not actively send charging requests to the communication control module 4-20 and only send their own status information (e.g., whether a power-receiving device 4-40 is connected) and the status information of the connected power-receiving device 4-40 (e.g., whether there is a battery pack inserted in the power-receiving device 4-40) to the CAN bus. Thus, during the charging process, all other transmission control modules 4-30, except for the one currently being charged, remain in a restricted communication status.
In one embodiment, during the charging process, the transmission control module 4-30 is also used to monitor the communication status between the power-receiving device 4-40 and the communication control module 4-20 and to determine the working status of the entire charging system. It also monitors the health status of the power-receiving device 4-40. When the working status of the entire charging system and/or the health status of the power-receiving device 4-40 becomes abnormal, the transmission control module 4-30 cuts off all connections between the power-receiving device 4-40 and the communication control module 4-20. It also displays the abnormal status on the display panel of the transmission control module 4-30 and informs the communication control module 4-20 to wait for the next power-receiving device 4-40 to be connected before continuing to work. The communication control module 4-20 calls each other transmission control module 4-30 via the CAN bus to determine if they need charging. When a transmission control module 4-30 with a power-receiving device 4-40 responds, the communication control module 4-20 charges the power-receiving device 4-40 connected to that transmission control module 4-30.
The charging system of the present application can be applied in various scenarios, which are described as follows:
In one scenario, the charger 4-10, communication integration box, and several transmission control modules 4-30 of the charging system can be deployed in a workshop, office, or other indoor environment to form a fixed charging system. Garden workers can transport all charging boxes indoors and connect them to the charging interfaces 4-34 of the transmission control modules 4-30 at night or after work, using the charging system to charge the battery packs in all the charging boxes.
In another scenario, the charger 4-10, communication integration box, and several transmission control modules 4-30 can be deployed on a trailer or truck to form a mobile charging system. The charging boxes can be placed on the trailer or truck and connected to the charging interfaces 4-34 of the transmission control modules 4-30. At night or after work, the trailer or truck can be parked near an AC socket, and garden workers can use an extension cord to power the charger 4-10, thus using the charging system to charge the battery packs in all the charging boxes.
In another scenario, the charger 4-10 and communication integration box can be placed on one truck, while several transmission control modules 4-30 are placed on different trucks to form a mobile charging system. The transmission control modules 4-30 and the charging boxes connected to their charging interfaces 4-34 are placed on the same truck. At night or after work, garden workers can use an extension cord to power the charger 4-10, thus using the charging system to charge the battery packs in all the charging boxes.
In another scenario, the charger 4-10, communication integration box, and several transmission control modules 4-30 of the charging system can be deployed in an outdoor environment, such as a building. Garden workers can park the trucks or trailers with the charging boxes next to the charging system and connect the charging boxes to the charging interfaces 4-34 of the transmission control modules 4-30 at night or after work, using the charging system to charge the battery packs in all the charging boxes.
In one embodiment, the electric vehicle 6-10 may be a lawn mower, sightseeing car, golf cart, or electric car, whether for road or off-road use. The first power device 6-11 is an internal battery of the electric vehicle 6-10, which is a high-voltage, high-capacity battery pack. The capacity of the first power device 6-11 ranges from 6 kWh to 40 kWh, for example, 8 kWh, 18 kWh, 24 kWh, 30 kWh, or 36 kWh. The energy density of the first power device 6-11 is greater than 100 Wh/kg.
In one embodiment, the second power device 6-30 is a small charging box, equipped with one or more removable battery packs, which are low-voltage, low-capacity battery packs 6-40 for handheld electric tools. The capacity of the second power device 6-30 is less than 8 kWh, for example, 4.8 kWh. Handheld electric tools may include handheld electric chainsaws, blowers, vacuums, drills, or pruners. In one specific embodiment, the second power device 6-30 is a 6-6 small charging box that can charge 6-6 low-voltage, low-capacity battery packs 6-40.
The voltage of the first power device 6-11 differs from that of the second power device 6-30, with the voltage of the first power device 6-11 being higher than that of the second power device 6-30. The capacity of the first power device 6-11 also differs from that of the second power device 6-30. Specifically, the capacity of the first power device 6-11 is greater than that of the second power device 6-30, where the capacity of the power device is defined as the original capacity when the battery pack is fully charged.
As shown in
In one embodiment, the voltage conversion circuit 6-20 is arranged in the current path from the first power device 6-11 to the second power device 6-30, meaning that the voltage conversion circuit 6-20 is arranged between the first power device 6-11 and the second power device 6-30.
In other embodiments, the voltage conversion circuit 6-20 may also be arranged within the first power device 6-11 or the second power device 6-30.
In one embodiment, the voltage conversion circuit 6-20 includes a unidirectional DC/DC module (it can also be a bidirectional DC/DC module) for stepping down the high-voltage electricity output by the first interface 6-12 to low-voltage electricity to charge the removable battery pack in the second power device 6-30. Using a step-down method can effectively reduce losses in the voltage conversion process and improve conversion efficiency. The DC/DC module can be either an isolated or non-isolated DC/DC module.
To further reduce losses in the voltage conversion process and improve conversion efficiency, the voltage conversion circuit 6-20 can use a non-isolated DC/DC module. Compared to isolated DC/DC modules, non-isolated DC/DC modules have less energy loss and higher efficiency during voltage conversion. Additionally, non-isolated DC/DC modules are smaller in size and lower in cost compared to isolated DC/DC modules because they do not require a transformer for electrical isolation between input and output.
In one embodiment, the second power device 6-30 is configured on the electric vehicle 6-10. The second power device 6-30 is connected to the first interface 6-12 via cables or connection terminals to receive the current flowing from the first interface 6-12. Of course, the second power device 6-30 can also be set up independently, for example, placed on the ground or a platform next to the electric vehicle 6-10.
When configured on the electric vehicle 6-10, it can appear in a concealed or partially exposed form, such as being placed on a platform of the electric vehicle 6-10, hung on a component of the electric vehicle 6-10, or removably stored in an enclosed space within the electric vehicle 6-10. This allows at least one interface of the second power device 6-30 to directly or indirectly receive the support from at least one component of the electric vehicle 6-10.
In one specific embodiment, the electric vehicle 6-10 is a lawn mower, equipped with a walking assembly and a cutting assembly. The first power device 6-11 is configured to be electrically connected to the walking assembly and/or the cutting assembly to drive the operation of the walking assembly and/or the cutting assembly.
The lawn mower has a platform for carrying objects, including a front carrying platform and/or a rear carrying platform. As shown in
In one embodiment, for convenience, a plug-in port can be directly set on the carrying platform as the first interface 6-12, and a connection terminal can be set on the second power device 6-30. When the second power device 6-30 is placed on the carrying platform, the connection terminal on the second power device 6-30 can be plugged into the plug-in port to achieve electrical connection.
Optionally, the power delivery system can also include some functional devices set on the electric vehicle 6-10 to expand the functions of the electric vehicle 6-10. The functional devices are functional accessories that can be directly driven by the first interface 6-12 of the electric vehicle 6-10. The power supply interface of the functional device is detachably connected to the first interface 6-12. The current flows from the first interface 6-12 to the functional device to drive the operation of the functional device. The functional devices can be a blower assembly or a snow sweeper assembly installed on the front end of the lawn mower.
The power delivery system of the present application can use the high-voltage, high-capacity battery pack of the electric vehicle 6-10 to charge the low-voltage, low-capacity battery packs 6-40 housed in the second power device 6-30 when there is no AC power supply outdoors. No additional AC/DC charger is needed, and the energy of the internal battery of the electric vehicle 6-10 can be diversely allocated and used. This not only allows for power sharing but also provides emergency power, forming a separate multi-use system, increasing product expandability, expanding application scenarios, suitable for product ecosystem construction, and having strong market adaptability. Additionally, when the second power device 6-30 charges multiple low-voltage, low-capacity battery packs 6-40, it can automatically allocate charging energy and selectively connect charging based on the number of battery packs actually connected.
In practical application scenarios, when the low-voltage, low-capacity battery pack 6-40 in a handheld electric tool is out of power, it can be removed from the handheld electric tool and placed in the second power device 6-30. The second power device 6-30 can then be connected to the first interface 6-12 via cables or connection terminals to receive the current flowing from the first interface 6-12 to charge the battery pack in the second power device 6-30. Once fully charged, it can be installed in the handheld electric tool to power the handheld electric tool, achieving the purpose of power sharing.
The first power device 6-11 is housed within the electric vehicle 6-10. The first interface 6-12, as a discharge interface, is electrically connected to the first power device 6-11. The second interface 6-13 is electrically connected to the first power device 6-11. The second interface 6-13 is independent of the first interface 6-12 and serves as a charging interface for the internal battery of the electric vehicle 6-10. The second interface 6-13 is electrically connected to the first power device 6-11.
The entire power delivery system has two states. In the first state, the second power device 6-30 is electrically connected to the first interface 6-12 to receive the current flowing from the first power device 6-11. In the second state, the second power device 6-30 is electrically connected to the second interface 6-13 to allow current to flow from the second power device 6-30 to the first power device 6-11. This enables not only charging the low-voltage, low-capacity battery packs 6-40 housed in the second power device 6-30 using the high-voltage, high-capacity battery pack of the electric vehicle 6-10 through the first interface 6-12, but also using the low-voltage, low-capacity battery packs 6-40 housed in the second power device 6-30 to supplement the high-voltage, high-capacity battery pack of the electric vehicle 6-10 through the second interface 6-13, achieving bidirectional power delivery.

Specifically, the capacity of the first power device 6-11 is greater than that of the second power device 6-30, where the capacity of the power device is defined as the original capacity when the battery pack is fully charged.
The first interface 6-12 is an interface set on the electric vehicle 6-10 for external power output, such as an ETO interface. The maximum current output by the first interface 6-12 is 6-100A, meaning that the current output by the first interface 6-12 is less than or equal to 6-100A, meeting the demand for high-power supply. It can be used to charge the low-voltage, low-capacity battery packs 6-40 in the second power device 6-30 or to power additional functional devices on the electric vehicle 6-10.
As shown in
The voltage conversion circuit 6-20 uses a unidirectional DC/DC module (it can also be a bidirectional DC/DC module) to step down the high-voltage electricity output by the first interface 6-12 to low-voltage electricity to charge the removable battery pack in the second power device 6-30.

In one optional embodiment, when the voltage conversion circuit 6-20 uses a unidirectional DC/DC module, another voltage conversion circuit can be arranged in the current path from the second power device 6-30 to the first power device 6-30 in the second state. When the voltage conversion circuit 6-20 uses a bidirectional DC/DC module, the same bidirectional DC/DC module can be used in the current path from the second power device 6-30 to the first power device 6-30 in the second state to step up the low-voltage electricity output by the second interface 6-13 to high-voltage electricity to supplement the first power device 6-11.

In practical applications, the power delivery system shown in
When the internal battery of the electric vehicle 6-10 is severely out of power outdoors, rendering it unable to move or operate, the low-voltage, low-capacity battery pack 6-40 carried with a handheld electric tool can be placed in the second power device 6-30.

In one embodiment, the waterproof and dustproof battery provided above includes a shell 10-1, a battery component 10-5, a cover plate 10-32, and a sealing layer 10-33. The shell 10-1 forms a storage cavity; the battery component 10-5 is set inside the storage cavity; the cover plate 10-32 is set on the outside of the shell, and a sealed cavity is formed between the cover plate 10-32 and the shell; the sealing layer 10-33 is formed in the sealed cavity through insert molding.
In a specific embodiment, the shell can include a main body and an end cap 10-3. The information display unit of the battery pack can be set on the end cap 10-3. Correspondingly, the cover plate 10-32 and the sealing layer 10-33 should also be set on the end cap 10-3. It should be understood that the installation position of the information display unit is not unique. For example, in other embodiments, the information display unit can also be set on the main body, and correspondingly, the cover plate 10-32 and the sealing layer 10-33 should also be set on the main body. The following detailed explanation of the technical solution of this application is made based on the scenario where the information display unit is set on the end cap 10-3.
In one embodiment, as shown in
In one embodiment, the cover plate 10-32 can be made of PC material, making it transparent or semi-transparent, pre-formed by injection molding, facilitating the display of content on the light board 10-4.
The aforementioned end cap 10-3 and cover plate 10-32 are pre-inserted into the mold, forming a sealed cavity between the cover plate 10-32 and the end cap. Plastic is injected into the sealed cavity through the injection head of the injection mold, finally forming the sealing layer 10-33. The sealing layer 10-33 forms a reliable integral unit with the end cap 10-3 and the cover plate 10-32 through insert molding, ensuring the overall sealing reliability of the upper end cap. In one embodiment of the application, the sealing layer 10-33 material can be made of PET. Preferably, corresponding hollow parts are set on the target areas of the sealing layer 10-33 on the end cap and the cover plate 10-32.
In one embodiment of the application, the target area can be a pressing part 10-331 for operating the battery pack. The cover plate 10-32 is provided with a first hollow part 10-321 corresponding to the pressing part 10-331. The end cap 10-3 is provided with a second hollow part 10-311 corresponding to the pressing part 10-331, with the pressing part 10-331 extending into the first hollow part 10-321.
When the pressing part 10-331 is arranged on the sealing layer 10-33, it should correspond to the position of the operation button on the light board inside the shell 10-1. When the pressing part 10-331 extends into the first hollow part 10-321, it allows the operator's fingers to extend into the first hollow part 10-321 to press the operation button.
In one embodiment of the application, various operation instruction patterns can be pre-set on the pressing part 10-331, such as a power start instruction pattern, etc.
In one embodiment of the application, the outer contour of the pressing part 10-331 can be any of circular, rectangular, or irregular shapes.
As shown in
In one embodiment of the application, the inside of the end cap 10-3 is provided with a button corresponding to the target area. The button can be set on the light board 10-4 and can be a button for operating the power switch or a button for operating the light board 10-4 switch.
To make the upper end cap of the battery pack more regular, in a preferred embodiment of the application, the outer side of the end cap 10-3 is provided with a receiving slot 10-34, the sealing layer 10-33 is housed in the receiving slot 10-34, and the cover plate 10-32 covers the slot opening of the receiving slot 10-34.

This invention proposes an energy storage device, which sets up a drainage structure inside the box, with each vent corresponding to the drainage structure. The drainage structure includes a water-blocking element, set opposite the vent, with a certain gap between the sidewall of the box with the vent. Additionally, a first drainage hole is set at the bottom of the box, located in the gap. When water enters through the vent, the water-blocking element blocks the rainwater or other liquids, directing them into the gap, and discharges them through the first drainage hole to effectively prevent rainwater or other liquids from entering the interior of the energy storage box, significantly improving the lifespan and safety of the energy storage device.
This invention proposes an energy storage device where the drainage structure blocks rainwater or other liquids and discharges them in time, preventing them from entering the interior of the box, ensuring the internal environment of the box remains dry and protecting the circuit board. Therefore, in this application, all circuit boards can be arranged as close to the bottom of the box as possible and can be arranged in the same horizontal plane inside the box, reducing the height occupied by the circuit boards and effectively lowering the overall height of the energy storage device, improving space utilization.
To facilitate securing the battery pack in the charging chamber for charging, a locking device is generally installed at the top of the charging chamber to lock the battery pack in place when inserted. However, in current designs, part of the locking device is integrated with the battery pack case, requiring the installation of the lock tongue from the back of the battery pack case, making the installation process complicated and inconvenient. The locking structure must first be installed from the back of the battery pack case and then assembled with the case and other structures. If the locking structure is damaged or needs maintenance, the entire battery pack case must be disassembled to access the locking structure, which is complex and cumbersome. Only the lock tongue and pivot can be removed and replaced in the locking structure.

It is understood that for battery packs with wireless charging functions, the conductive terminal can be a wireless power transmission module. When the battery pack is inserted into the charging chamber, the wireless power receiving module of the battery pack couples with the wireless power transmission module in the charging chamber, connecting the battery pack to the charging circuit of the energy storage device to obtain charging current. In other embodiments, when the battery pack 12-40 is inserted into the charging chamber 12-131, the battery pack 12-40 can connect with the energy storage device 12-100 via conductive terminals or wireless power transmission modules, allowing the battery pack 12-40 to output current through other output ports on the energy storage device 12-100.
It should be noted that the battery pack described can be a cylindrical cell battery pack or a soft pack battery.
The battery pack described includes a battery encased in a flexible cover, allowing it to conform to various shapes and surfaces, which is particularly useful in applications like wearable technology and foldable devices. The flexible cover is made from advanced materials, such as polymer composites or other flexible substrates, that can bend and twist without affecting the battery's performance or safety. This design approach is critical for integrating power sources into products with non-standard shapes or where a lightweight, adaptable solution is needed.
To create a flexible battery pack, the manufacturing process involves several key steps. One of the primary techniques is thin-film technology, where active materials are deposited onto a flexible substrate. This method allows the battery to maintain its electrochemical properties even when bent or flexed. The flexible substrate typically consists of materials like polymer films that provide both flexibility and mechanical strength. Additionally, the electrodes are designed to withstand deformation without losing conductivity, often using materials like carbon nanotubes or conductive polymers.
The encapsulation process for flexible batteries is essential for protecting the internal components from environmental factors like moisture and oxygen. The flexible cover must be carefully engineered to seal the battery while allowing for mechanical flexibility. Techniques such as lamination or coating with barrier films are commonly used to achieve this. These protective layers ensure that the battery can function reliably in various conditions, including those where bending or twisting is frequent.
Safety considerations are integral to the design of flexible battery packs. The materials and construction must ensure that the battery can withstand mechanical stresses without leading to failures such as short circuits or leaks. Safety mechanisms, such as pressure-sensitive shutoffs and thermal management systems, are often incorporated to prevent overheating and ensure stable operation under different conditions. This makes the battery suitable for use in a wide range of applications where flexibility and reliability are crucial.
In summary, manufacturing a flexible battery pack involves the integration of thin-film technology, flexible substrates, and advanced encapsulation techniques. The result is a battery that can bend and flex without compromising performance, making it ideal for innovative electronic devices that require adaptable power sources. The process requires careful selection of materials and precise engineering to ensure that the battery meets both performance and safety standards.
Flexible cover battery packs offer several significant advantages over traditional rigid battery designs, particularly in applications where space, shape, and adaptability are key concerns. One of the primary benefits is their ability to conform to non-standard and irregular shapes. This makes them ideal for integration into devices like wearable technology, where the battery needs to fit into small, curved, or flexible spaces. The flexible cover allows the battery to bend and adapt to the contours of the device, providing a seamless integration without compromising the form factor.
Another advantage of flexible battery packs is their lightweight nature. Traditional battery packs often require rigid casings that add weight to the device, but flexible covers eliminate the need for such heavy encasements. This reduction in weight is particularly beneficial in portable electronics, where every gram counts. It allows engineers to design lighter and more ergonomic devices, improving user comfort and device portability without sacrificing battery capacity or performance.
Flexible cover battery packs also offer improved durability in certain applications. The flexible materials used in these batteries are typically more resistant to mechanical stress, such as bending, twisting, or compressing, compared to rigid casings. This resilience makes them more suitable for environments where the device may be subjected to repeated flexing or movement, such as in smart clothing or medical wearables. The ability to withstand mechanical deformation without damage extends the operational life of both the battery and the device it powers.
In terms of manufacturing, flexible cover battery packs can be produced using roll-to-roll processing, a method commonly used in the production of flexible electronics. This technique is efficient and scalable, allowing for the mass production of flexible batteries with consistent quality. Roll-to-roll processing also enables the integration of various components, such as electrodes and encapsulation layers, in a continuous and streamlined process, reducing production costs and time.
Finally, the adaptability of flexible cover battery packs opens up new possibilities for innovation in product design. Engineers are no longer constrained by the limitations of rigid battery shapes and sizes. Instead, they can design devices with unique and ergonomic forms, knowing that the battery can be tailored to fit the available space. This flexibility encourages creativity in the design process, leading to the development of more advanced and user-friendly products across various industries, from consumer electronics to healthcare devices.
